次のようなご質問をメールでいただきました。
わかるかた、おられますでしょうか？
I'm using uplatex for vertical typesetting, using manyfoot and marginpar together seems to cause some problem. Below is a minimal code that reproduce the problem:
\documentclass{utbook} % works if \documentclass{book} is used%
\usepackage[para*]{manyfoot}
\DeclareNewFootnote[para]{A}[default]
\begin{document}
Lorem ipsum dolor sit amet, consectetur adipiscing
elit.\FootnotetextA{abc} % works if no footnotes used
Aliquam gravida nec nulla sit amet
rutrum.
\marginpar[]{abc}%
\end{document}
The file compiles if I remove manyfoot.
manyfoot パッケージの類は縦組みを考慮していなくても仕方ありませんね．
とりあえず，次の細工を manyfoot パッケージの読み込みの直後に入れてみるとどうでしょうか？
\makeatletter
\def\MFL@reinsout#1#2{\ifvoid#2\else
\ifnum\count\@currbox>\z@
\advance\@pageht \ht#2%
\advance\@pageht \skip#2%
\advance\@pageht \dp#2%
\fi
\insert#2{\@@check@dir#2\unvbox#2}%
\fi
}
\expandafter\ifx\csname iftbox\endcsname\relax
\let\@@check@dir\@gobble
\else
\edef\@@check@dir#1{%
\expandafter\noexpand\csname iftbox\endcsname #1 \tate
\expandafter\noexpand\csname else\endcsname \yoko
\expandafter\noexpand\csname fi\endcsname}%
\fi
\makeatother
Original correspondent who sent the email to Prof. Okumura here. Apologies for typing English here as I don't know enough of Japanese and do not want to disrespect the language by posting machine translated results.
Many thanks to しっぽ 愛好家 I verified in my code and it compiles.
